3D Slider Widget that changes Length, Width, and Height in Virtual Reality

I am trying to make a 3D slider widget appear in Virtual Reality after selecting an object. For example, the left trigger is pressed and the widget pops up when clicking over the object. I want the widget to display the length, width, and height of an object. I want the individual left to right sliders appear for the length, width, and height. Upon sliding the length, width, or height sliders from the left to right I want the object’s size to change. I also want the displayed length, width, and or height to change as the slider is moved. Is this possible? If it is could someone possibly give a step by step?
